Answer is x = -7 and x = -3
<span> x2 + 10x = -21
</span><span> x2 + 10x + 21 = 0
</span>(x +3) (x +7) = 0
(x +3) = 0
and
(x + 7) = 0
so x = - 3 and x = -7
Answer:
choice C
Step-by-step explanation:
First, you need to know that this is the Fibonacci Sequence, a series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... where the next number is found by adding up the two numbers before it.
So, if we want to find the next 3 terms...
5+8=13
8+13=21
13+21=34.
So, your answer is choice C

Answer:
7x-y=3 (1)
y=x+3 (2)
Replace y = x + 3 in (1) => 7x- (x + 3) = 3
=> 6x-3 = 3 => x = 1 => instead of (2) => y = 4
So: x = 1, y = 4 is the solution of the system of equations
